SKYLIGHT OR TRANSOM LIFTER.

SPECIFICATION forming part of Letters Patent No. 770,316, dated September 20, 1904.

Application filed May 12, 1904:. Serial No. 207,597. (No model.)

To all whom, it may concern:

Be it known that I, KARL RoDELs'rAB, master locksmith, a citizen of the German Empire,residing at Rheinstrasse 13, in the town of Bruchsal, Grand Duchy of Baden, Germany, have invented new and useful Improvements in Contrivances for Operating Windows, entitled Contrivance for Secure Shutting and Better Cleaning of Skylight-Windows, of which the following is a specification.

The subject of the present invention is a contrivance attached to skylight windows which insu res a secure closing and better cleaning of the same.' In the accompanying drawings this contrivance is delineated in five figures.

Figure 1 gives a perspective View, in particular exhibiting the parts which serve to attain a secure closing of the window; Fig. 2, a vertical section displaying such parts with the window closed; Fig. 3, a perspective view of a portion of the contrivance, showing more especially those parts which aid in obtaining a better cleaning of the window. Figs.

4 and 5 are perspective views which display the slide-bolt fitting and its details.

The parts specially serving to shut and hold the window securely shut consist mainly in a stout axle b, so arranged as to pass through the hinge-shells of the Window and through the inner tie-holes of rods 0 and d and c and d, which rods relatedly with the surface of the window form triangles. As displayed, if the window be actuated from the point of junction 6 on the right-handside or from the point of junction 0 on the left-hand side with the object of closing it, the window will invariably shut, fitting tightly and equally into its frame f. To limit the aperture shoulders g can be ad justably and removably fixed on the outer ends of the axle b. When the window is opened to the greatest extent desired,

these shoulders bring up against the lower portion of the frame. Obviously athorough cleaning of the window will be greatly facilitated if it can be turned over completely downward. This is here effected by means of a detachable connection of the upper ends of the rods d and d with the window a. To serve this purpose, a slide-bolt fitting h, Figs. 3, 4, and 5 is employed. A bolt 11 slides to and fro in the barrel h of this fitting, Figs. 4 and 5. Such bolt makes the connection between the rod d and the window a a detachable connection. The heft c", by which said bolt is worked, runs in a slit in, out along the barrel. A notch k is cut in this slit near' its outer end. The heft of the bolt rests in such notch when the bolt is pushed outward to form the connection spoken of. The heft of the bolt is furnished with a ball-like or cross head for convenience of operation.

What I claim as my invention, and desire to secure by Letters Patent, is

In a contrivance to obtain secure shutting and better cleaning of skylight-windows, the combination of a hinge-axle 6 having removable and adjustable shoulders g g, rodsc 0 connected at their inner tie-holes with said axle, and rods d cl detachably connected at their upper ends with the window a and at their lower ends joined to foregoing rods at the point of junction 6, with a slide-bolt fitting ]1. having a barrel it in which a slit in is cut with a notch if out in said slit, and a bolt 2' having a headed heft i and sliding in such barrel, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

KARL RODELSTAB.
